A fingering

"Mmmm," is all Kate can say, her eyes closed. You can feel her filled with lust, her loins aching to be touched and played with. You oblige, and move a hand down, brushing her stomach, to her pussy.

You give her clit a flick, and she moans, her left hand coming up to prop her against the wall. You can make her orgasm with just the tip of your finger, or you could keep her on the brink for hours and hours. You slide one finger into her steaming pussy, sending wave after wave of pleasure through her, but keeping her from climax.

"Oh John," Kate murmurs, "I'm so - ah - oh my god."
